time format (System default) determines whether a 12-hour 
(AM/PM) or 24-hour format is used. 

seconds format (1 sec) determines how many digits of precision 
are displayed for timestamps.

file path is the name of the spreadsheet file to store the historical data. If 
file path is empty (default value), or is Not A Path, the VI displays a file 
dialog box from which you can select a file. Error 43 occurs if the user 
cancels the dialog.

historical data is the set of historical data trends to convert to spreadsheet 
format.

historical trend describes historical trends for the inpout tag 
names, read from the historical database. The data in the trends 
start at the date and time specifiied by start timestamp, and end 
at the date and time specified by stop timestamp.

tag names is the list of tag names corresponding to the historical trends. 
These tag names are used as column headers when converted into 
spreadsheet format.

error in (no error) is a cluster that describes the error status before this VI 
executes. For more information about this control, see the section 

 in this appendix. 

sample interval (1 sec) determines the time interval for each spreadsheet 
row. If unwired, a spreadsheet row is created for each one-second interval.

start/stop time info describes the settings used to decimate the data for 
export to spreadsheet.

error out is a cluster that describes the error status after this VI executes. 
For more information about this indicator, see the section 

 in this appendix.

file path out is the name of the spreadsheet file in which the historical date 
is stored.
